I think Vitali. Wlad is exceptionally talented, but what are his best five wins? What have they accomplished? It could be argued that giving Lewis a hard fight is better than anything Wlad has ever done - or is ever able to do given the opposition currently available - unless he fights big bro.
Wlad... by far. Their records and accomplishments... as well as opponents that they have beaten and WHEN they beat them speak for themselves.
WHAT? Wlad beat Sam Peter when Peter was in great shape and was an undefeated #1 contender. He also knockout out Calvin Brock when Brock was an undefeated top contender. He also beat Sultan Ibragimov, when Ibragimov was an Undefeated CHAMPION.... as well as beating Chagaev as he was also an undefeated (true WBA Champ). He also beat Chris Byrd TWICE, including when Byrd was the longest standing Champion in the division as well as the Ring Magazine #1 ranked Heavyweight in the world. Let alone dominant wins over contenders or former Champs like McCline, Rahman, Austin, Thompson, Brewster, Mercer, Botha, Barrett, Jefferson, ect.... Not only has he done much more than Vitali... he has also done much more at 33 years of age than Lennox Lewis did at 33 years of age. Wlad has been ruling this division for about 4 years and nobody has even come close to beating him in almost 6 years.
This is tough idk. I do know that big brother Vitali avenged several of his brother's losses so it's tough to say who's better. I think Wlad is a better fighter and has more skills, but Vitali is meaner, tougher, and more confident.
Wlad. Worse losses, sure, but more quality wins to make up for it. Also, not injury-prone which allowed him to face and beat more of the contenders/beltholders around HW.
Great post. Very well researched. It's almost stunning that some so-called boxing fans can read your post and not consider Wlad as an all time great heavyweight. Just his sheer dominance of the heavy division for four years is impressive but also his list of victories over top-rated undefeated heavyweights over his long twelve year career as a pro fighter is astonishing; the guy backs down to nobody and fights anybody who the fans or the writers think are his toughest competition. At age 33 he is still an awesome physical specimen due to his work ethic and determination. History will record Wlad as one of the greats.
neither is ATG material (top 100), but Wlad has the better resume of the two, plus he never quit on his stool.
